  The top voted answer explains that the premise of the question and therefore the title of the submission is wrong.

    So you missed the answer from ridiculous_fish there: on Power PC CPU's doing floating point comparisons the speeds are actually different. That's a perfect counterexample for your claim that "the premise is wrong." Detailed explanation about reasons was given by Lukas.

      The Detailed Explanation given by Lucas concludes: So, on some machines, using a "less than" comparison might save one machine instruction. This was relevant in the era of sub-megahertz processor speed and 1:1 cpu-to-memory speed ratios, but is almost totally irrelevant today.

    I wish I knew, but I got downvoted for a constructive attempt at pointing it out.

  What was that law that said that all titles that ended with a question mark can be answered "No"?

  It may or may not be.. Its dependent on CPU, and Compiler.
